This single-center retrospective study of 186 patients undergoing general anesthesia found that a lower minimum intraoperative perfusion index (PI min) is significantly associated with end-of-surgery hyperlactatemia, suggesting PI min may serve as a simple marker for hypoperfusion-related metabolic stress despite its modest discriminative performance.
This prospective single-arm study of 12 Saudi patients demonstrates that radiofrequency ablation turbinate reduction is an effective treatment for rhinitis medicamentosa, successfully enabling complete decongestant withdrawal and significantly improving nasal obstruction and quality of life.
This global study utilizing large language models to analyze free-text survey responses from over 3,700 unvaccinated individuals reveals that COVID-19 vaccine refusal is primarily driven by specific technical concerns regarding mRNA safety and institutional mistrust rather than general anti-vaccination ideology, suggesting that transparent communication addressing these specific fears may be more effective than enforcement.
This study demonstrates that violet light induces apoptosis in chordoma cells by increasing reactive oxygen species levels and triggering mitochondrial damage, suggesting a promising new therapeutic approach for this radiotherapy-resistant tumor.
This feasibility study evaluated the usability and trust of a virtual reality AVATAR therapy interface across three groups, finding that while the system is generally user-friendly, individuals experiencing auditory verbal hallucinations perceive the avatar creation and interaction process as significantly more challenging than control and healthy participants.
This observational study demonstrates that a hybrid simulation training program, combining educational videos, role-playing with actors, and multidisciplinary debriefing, significantly reduced healthcare professionals' anxiety levels regarding parental presence during critical NICU events, though the findings are limited by the lack of a control group.
This retrospective study of 432 patients with large artery atherosclerotic ischemic stroke demonstrates that an elevated admission non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol ratio (NHHR) is an independent predictor of early neurological deterioration, suggesting its utility as a simple biomarker for early risk stratification.
This 2025 cross-sectional study at the University of Gondar Comprehensive Specialized Hospital in Northwest Ethiopia found that maternal near miss occurs in 14.3% of admitted women following armed conflict, with significant associations identified for primiparity, lack of antenatal care, and delays in seeking or receiving care.
This scoping review maps diverse interventions supporting underrepresented minority learners in surgery, finding that while such programs are increasingly common and improve short-term metrics like interest and confidence, their impact is limited by inconsistent definitions and methodologies, highlighting the need for standardized, longitudinal, and institutionally embedded strategies to achieve durable representation gains.
A study of French medical students reveals that adequate AI knowledge does not improve passively with clinical training stage or specialty interest, highlighting the need for explicit AI education integrated into undergraduate medical curricula.
